After that your son will share your Gold and Game Pass as well as digital game purchases on your account. If this is your first time getting an Xbox One then I would definitely recommend also signing up for Xbox Rewards via this link https://account.microsoft.com/rewards

You're right, you need to set these two accounts home Xbox on the console that you won't use, the way you said it, and all the features that one account has, except for game discounts, the other console will have, as well as that adding content is automatic

Hi, yes you are right.

I have only one little precisation for you, after you have set your sons xbox as your xbox home, they will be able to play all the games bought from your account, you don't need to buy a game through your sons xbox, but you need to buy it with your account,
also from smartphone or PC, the only important thing is that the game (or the subscriptions) must be purchased/activated from your account.

With this setting, you (and only you) will be able to play on your xbox one x with all the games purchased for your account, but if your son try to play on your xbox one x he cannot play any of the your games.

You can also set the xbox one x as your sons xbox home, doing this will let you play your sons game on the one x

Absolutely brilliant guys. Thank you very much indeed 😀😀😀😀

You can't share across two consoles. The sharing feature is for those using the same console.
